To all whom t 'may ron/cerny."

Be it known that l, Royan Gnar'ron, ot the post-offce of Mount Charles, in the county ol" Peel, in the Province of Ontario, Canada, have invented certain new and useful lmprovements in Cattlc-Stanchions, of which the following is the speeilication.

My invention relates to improvements in cattle stanchions, and its object is to provide a set of stanchions which can be opened or closed `either` simultaneously or one at a time, so that either the whole or any number of animals can be admitted or released as desired. i

A furtherobject is to produce a set of stanchions, which are cheap, and easily constructed and at the same time very durable, and it consists essentially of a rigid framework provided with horizontal upper and lower members, a plurality of vertil bars pivotally connected at their lower ends to the aforesaid .lower horizontal members, horizontal longitudinally movable members, inclined bars pivoted at their lower ends in the horizontal lower members and at their upper ends to the horizontf.1 longitudinally movable members, which are thereby en abled to swing parallel to the upper horizontal members of the frame, a lever loosely connected to one of the aforesaid inclined members, whereby such member may be operated, a latch to which said lever is conneeted, anengag'ing projection extending.

from the horizontally longitidinaliy moi .ith the said ftndinal movement :neinln'frs le uned to open non, as hereinafter more particuoribeiil by the following` specitication.

fl and il bers.

The members Q and 2 and'S and 3 are rigidly connected at one end to the vertical members el, Ll and 5, and at the other end to the vertical member 6. The members 2 and 2, and 3 and 3 are also rividly eonneeted intermediately of their en th to the uprights S, l), and-9. The mem ers 5, 6, and 8 serve to separate the horizontal members, thereby leaving an intervening space between such members.

l0 and l0 are longitudinal members eX- tending' between'the members 9 and 9. 7 and T are rectangular blocks inserted and suitably secured between the members l0 and 10 so as to forni an interveningspace 10 between such members. il and ll are inclined bars pivotally connected at their lower ends between i lie horizontal melnbers and 2 by the pivo bolts 13 and 13 passing;` through the horizontal members 2 and if and the said inclined bars. ln proximity to their upper ends the inclined bars ll and ll are pivotally connected between 'the nir-fn bers lil and 1W by the bolts l2 and l?! p inv through such members and through the are the upper horizontal niemscription that the horizontally swinging' bars l0 and l0 are supported by the inclined liars ll and li.

the swinging member l and normally en gages with the latch bar 2l and prevents the swingin members l0 and l0 from moving in the irection indicated by arrow, so 5 as to open out the stanchion bars 26.

23 isa depending hook catch in which the depending lever l5 is designed to normally rest.

24. is a depending bar having a notched lower `end designed to receive the lever in vthe open position of the stanchion.

25 and 26 are upright bars between each pair of which the neck of an animal is ininserted 'and held. The'rods 25 are pivotally connected to the members 2 and 2 of the frame by bolts 27, their upper ends which rest against the latches 28 being beveled as s own in Fig. 2. The rods are pressed against the latches 28 by means of springs 20 29 as shown in Fig. 2. y

ln Fig. 5, lisi-shown a detail of one of the latches which are suppliedmwith hinges 30 'by means of which they` are connectedv tothe frame as shown in Fig. l. These latches 25 are provided with inclined curved portions 3l whichgcoact with the beveled portions of the uprights 25. The rods 26 are longer than the rods 25 and extend between and above the members'lO and 10. The rods 26 3Q are pivotally connected to the frame at their lower ends by means of' pins 32. The pins 32 are formed with an end portion 32 turned at right angles-to the main portion of the pin and vforming a handle. At the y9,5 oposite end of the pin, a lug 322 is proed, extending at right angles therefrom. A plate 323 is secured by screws extending through-holes 324 to the member 2. rlhe A plate .323 is provided with holes 33 having 4o slotted portions 332 extending vertically upwardly therefrom. To insert the pin 32 through one of the holes 33 I turn the pin so that the lug 322 faces upwardly registeringv with the slot 332 and thenpass the pin through one of the holes 33 and through corresponding holes in members 2 and 2. I then give the pin a half turn so as to carry the lug S22-out of alinement with the slot `332. In thisfposit-ion it is impossible for the pinto work loose; By inserting the pin 32 in dierent holes 33, t-he distance between the rods 25\ and 26 canbe altered at will,-

the object being to provide forcows having di'erent sized necks.

The iipper horizontal members 3 and 3 and the swinging members l() and l0 are provided with a corresponding ser-ies of oles 34e and 35 into whichv are inserted bolts 3G, see Fig. 3, having a coarse screw thread 50 formed in the shank thereof, the object of this thread being to provide a.- rough surface which will prevent the pin from slipping out. Three oie these pins are used and are inserted in either set or' holes according 5 to the result desired, one of them being Ain- 'fortable as possible l make the distance beclaves serted on either side of the rod 26 which thus passes up between them. The operation of my stanchion is as follows. Suppose that, as shown in the ldrawings, the stanchions are closed and it is desired to throw them open simultaneously. To do this, the pins 36 are inserted in a palr oi' holes 35, one on either side of the rod 2G. The lever l5 is then lifted from the catch QSand slightly depressed. This raises the 7 latch 2l thereby releasing the swinging members l0 and l0. The lever is thenmoved horizontally to the right cnrryin with it the inclined rod ll which swings t e members l0 and 10 longitudinally carrying with 80 them the upper ends ofthe rods 26. By the above operation the stanchions are opened simultaneously permitting the cattle to insert their heads between the rods 25 and 26. The stanchions may then be closed by S5 an exactly similar operation as-already described performed in the reverse order. lf when the stanchionshave been closedt is found that one sof the cows is not in-its place, that particular stanchion can at oncggo be opened by simply raising the latch 28S when the rod 25 islimmediately drawn to one side by tlie spring 29 thus opening the' stanchion. ln a similar manner any cow can be liberated Without opening all the stanchions.

When yit is desired to close the stanchions after one of the cows has been liberated as described, the rod 25. is pushed back into place, the beveled end coming into Contact with the curved rportion 31 of the latch 28, forcing the latter up until the rod is in its normal position when the latch falls by its own weight alud secures the rod. Again iff it is desired toretain one of the cows and' liberate all the rest, the left hand pin 36 is removed from the holes in l the swinging member which correspond to the stanchion in question aml is inserted in the right hand cles in the members 3 anr The result of this is that when the Swingin member is moved it does not carry I.the ro 26 with it and that stauchion remains closed.

In order that t-he cows may be as comtween the upper bar of the horizontal meinbers 3 and 3 and the lowerpair ofhorizontal members 2 and l2 greater than is absolutely necessary, in other words, the length of the stanchion bars 25 and 26 is greater than is necessary. It is also providedthat the rods 25 and 26 move very loosely on the pins 27 and 32 so that the rods may be sprung apart by the cows to a certain extent.

lt is always more dillicult to close the stanchions when the cows arefinv position than it is to open them, as in oening them there is no bearing pressure against the .rods 25. in order to obviate this the rods ll and il are placed on a slant as shownJ this be-y 12C inox found .in practice to overcome the above di culty.

Another advantage attending the use' of niy stanehion is that. in the operation of milking the cows it is not necessary to crowd in between them, when each cow-is milked .it can be released by .simply releasing the corresponding latch 2S.

Whatl claim as my invention is:

l. ln a cattle stanchion, the combination 'with the rigid framework formed by two horizontal upper members and two horizontal lower members, the said upper and lower members being separated from each other so as to have an open space between them, vertical end members to which are rigidly attached't-he horizontal members, a plurality of vertical stanchion bars disposed in pairs and having their lower ends pivoted between the said lower horizontal members and their upperends extending through the opening between the upper horizontal members, a pair of horizontal swinging members, spacing blocks secured between them forming an intervening space through which one of each pair of the vertical stanchion bars pass, engaging means between the said bars and the swinging members, inclined bars extending through the opening between the swinging members and pivotally connected on their lower ends between the lower horizontal members 4and at their upper ends to the swinging members, and means whereby the swinging members are swung longitudinally through an\arc in a vertical plane, as and for the purpose specified.

2. In a device of the class described, the combination with'the rigid framework, of a series of vertical bars pivoted in the Ytramework and a second series of vertical bars pivoted in the framework and designed to cowith the aforesaid vertical bars, inclined bars also pivoted in the framework and a pair of swinging horizontal members carried by the inclined bars and engaging one of the series of vertical bars aforesaid and means whereby the horizontal nieinbers'may be swung longitudinally through an arc in a vertical plane, as and for the purpose specified.

3. A cattle stancliion comprising a, rigid framework, a swinging member having holes extending therethrough, a plurality of vertical bars disposed in pairs and pivoted in the frame, one bar in each pair being longer than the other and passing through the swinging member, threaded pinsI passing through holes in the swinging member on either side ot' the aforesaid bar, inclined bars pivoted at their lower ends in the frame and pivoted in Apro\iinity to their upper ends in the swinging member, one of the inclined bars extending upwardly above the swinging members, a lever pivoted at one end, an eye secured to the lever through which the upper end ofthe inclined member passes, a latch attached to the frame and connecting means between the latch and lever designed to operate the latch, a stop projection formed oir the horizontal swinging member designed to coact with the latch to prevent movement tending to -spread each pair of pivot bars apart as and for the purpose specified.

4t. In a device of the class described, the combination with theupper and lower horizontal members connected together and forming a rigid frame, of longitudinally swinging members, bars pivotally connected thereto and to the lower horizontal members, co-acting pairs of uprights, one member of each pair having a beveled upper end and all ot' said uprights .being connected to the lower vmembers oi" the tramo, and latches having beveled portions co-acting with the bevel portions of the uprights and designed to allow such nprights te pass into the locked position so as to prevent the opening ot' the stanchioii.
